Automatic Term Extraction in Technical Domain using Part-of-Speech and Common Word Features
Published in Association for Computing Machinery (ACM) Symposium DocEng, 2018
Extracting key terms from technical documents allows us to write effective documentation that is specific and clear, with minimum ambiguity and confusion caused by nearly synonymous but different terms. We present a method for Automatic Term Extraction (ATE) for the technical domain based on the use of part-of-speech features and common words information that has shown comparable or better results to the reported state of the art results.

A Natural Language Model for Generating PDDL
Published in The International Conference on Automated Planning and Scheduling (ICAPS) , 2021
The goal of this preliminary work is to predict the next completion in PDDL code, based on previous and surrounding text. The ability to generate PDDL code will be extremely useful to PDDL practitioners for the purpose of solving planning problems. It further opens the door to providing a source of inspiration for the modeller. The main contribution of our approach is a language model built using Recurrent Neural Networks (RNNs) that is trained on existing PDDL domains, which can be used to generate PDDL-like code

TattleTale: Storytelling with Planning and Large Language Models
Published in The International Conference on Automated Planning and Scheduling (ICAPS) , 2022
We explore how automated planning can be applied to Natural Language text generation in order to create narratives (stories) that are coherent and believable. Our work represents a key first step towards the novel application of planning technology to a neuro-symbolic approach for effective story generation.

Does Robin Hood Use a Lightsaber?: Automated Planning for Storytelling
Published in Twenty-Seventh AAAI/SIGAI Doctoral Consortium, Association for the Advancement of Artificial Intelligence (AAAI) , 2024
While recent work has shown that LLMs can successfully be used for narrative generation, they lack coherence and can be prone to repetition and stilted language. Automated Planning can therefore be combined with Natural Language text generation to create narratives (stories) that are logical, coherent, and believable.

Want To Choose Your Own Adventure? Then First Make a Plan.
Published in The 37th Canadian Conference on Artificial Intelligence (Canadian AI), 2024
We combine the fields of Automated Planning and Text Generation to show how text-based interactive Choose Your Own Adventure (CYOA) stories can be created using LLMs in conjunction with Fully Observable Non-Deterministic (FOND) based Automated Planning.

Large Language Models are Incoherent Storytellers.
Published in The 37th Canadian Conference on Artificial Intelligence (Canadian AI), 2024
By combining Automated Planning with Natural Language Text Generation by LLMs we can create logical, believable, and coherent stories that can be used in a wide variety of domains, for a large range of applications.

Automatic Term Extraction in Technical Domain using Part-of-Speech and Common Word Features
Published:
Extracting key terms from technical documents allows us to write effective documentation that is specific and clear, with minimum ambiguity and confusion caused by nearly synonymous but different terms. For instance, in order to avoid confusion, the same object should not be referred to by two different names (e.g. “hydraulic oil filter”). In the modern world of commerce, clear terminology is the hallmark of successful RFPs (Requests for Proposal) and is therefore a key to the growth of competitive organizations. While Automatic Term Extraction (ATE) is a well-developed area of study, its applications in the technical domain have been sparse and constrained to certain narrow areas such as the biomedical research domain. We present a method for Automatic Term Extraction (ATE) for the technical domain based on the use of part-of-speech features and common words information.
A Natural Language Model for Generating PDDL
Published:
The goal of this preliminary work is to predict the next completion in PDDL code, based on previous and surrounding text. Generating valid PDDL code is a key component in creating robust planners. Thus, the ability to generate PDDL code will be extremely useful to PDDL practitioners for the purpose of solving planning problems. It further opens the door to providing a source of inspiration for the modeller. The main contribution of our approach is a language model built using Recurrent Neural Networks (RNNs) that is trained on existing PDDL domains, which can be used to generate PDDL-like code.
TattleTale: Storytelling with Planning and Large Language Models
Published:
We demonstrate the use of a planning model that provides scaffolding to an LLM so that its language generation is context dependent in order to create more coherent and believable stories in a variety of domains.
